Pulsar Cluster Migration Best Practices - In-Place vs. Geo-Replication Approaches

Learn essential strategies for migrating Apache Pulsar clusters in modern cloud environments through this comprehensive conference talk. Explore two primary migration approaches—in-place migration and geo-replication—to effectively handle geographic region switches, infrastructure upgrades, or transitions from self-hosted to managed services. Discover the benefits and drawbacks of each strategy, including how in-place migration maintains single data environments while simplifying client interactions, and how geo-replication leverages built-in features for automated data replication without requiring network connectivity between clusters. Examine real-world case studies, including StreamNative's successful AWS customer migrations that reduced infrastructure costs and improved technical support. Master operational considerations such as resource requirements, potential bottlenecks, and performance optimization techniques to ensure data integrity while controlling costs. Gain practical insights into handling different metadata stores, managing resource constraints, and addressing common migration challenges through detailed Q&A scenarios covering comparisons with Kafka's MirrorMaker and solutions for managed cluster environments.
